Vintage Illuminated Watches, Clocks and Dials Emitting Radon

By | News | No Comments

In the beginning of the 20th century, scientists developed a way to mix “radium 226” with paint. This created ‘radioluminescent paint’. This breakthrough led to the new product being applied to clocks and telephones. Even airplane instrumentation panels (all now considered to be vintage), enabling the devices to glow in the dark.

However the new approach led to unforeseen circumstances. By 1925 a group of radium painters, later referred to as the Radium Girls, sued their employer over health issues. This was believed to be stemming from the ingestion of radium through a practice called ‘pointing’ their brushes. They would lick the ends of the brushes to refine the bristles into a point. Subsequently ingesting radium remnants from the brush. As a result, by 1930 ‘pointing’ brushes was no longer done by mouth and there were no more incidences of malignancy due to radium. This led most people to believe that radium was not a health risk provided you did not consume it.

Sixty years later researchers from the University of Northampton wondered whether since radium decays into radon gas, “vintage” clocks, watches, phones and such items, previously coated in radium paint could influence radon gas levels as the radium naturally decays.

The study was performed in a small bedroom and consisted of measuring the radon gas level for a baseline. Then adding 30 radium dial watches to the room to see how much the radon level would change, if at all. Upon retesting it was discovered that the room’s radon level rose to 134 times the level at which the EPA (United States Environmental Protection Agency) recommends action.

The data from this first study of its kind indicates a previously unconsidered risk. This was from owning, collecting, and storing radium dial watches or other items coated in radium-infused paint.

So keep calm, and think before you go vintage.

Many homes have basement areas. Whether finished or not there is always a potential for radon to enter your home through the basement. Not all homes will have every radon entry point shown, but the image shows the most common ones. Any one of these entry points could contribute to a high radon gas level in the home.

Testing for radon is the only  way to know if your home has high levels of dangerous radon gas, a class A carcinogen that causes lung cancer.

Radon can be a health risk in ordinary workplaces

By | News | No Comments

Workplace radon is a so-called “inert” gas that emits ionising radiation, which means that radon is radioactive. Therefore it is also a potent risk. Ionising radiation can cause damage to cells, which in turn leads to illnesses such as cancer. Lung cancer is the most common form of cancer that can be caused by radon.
Radon gas is an element that can come directly from the ground because radon is created when uranium decays. It therefore exists naturally, which can affect properties that have basements with poor insulation. Or that are otherwise in direct contact with the ground.

How do you know if radon is a health risk in the workplace?

It is easy to measure radon levels in the workplace to see whether the value exceeds the limit above which radon is estimated to be a health risk. If the radon level is above 400 Bq/m³, it could mean that spending too much time in the property entails a direct health risk.

Measuring radon levels is simple and straightforward using radon boxes placed in rooms in which people spend the most time. In the case of homes, they are normally placed in bedrooms and living rooms. In the case of a workplace, it is a question of finding similar places in which people spend a lot of time.

There are two different kinds of radon boxes available: those offering long-term measurement or those offering short-term measurement. Long-term measurement must be carried out during the winter months and needs to last for two to three months to provide the most complete results possible for radon levels in the property. A so-called “annual average value” for the radon levels can be obtained from long-term measurement. There are also boxes that are used to carry out short-term measurements. A measurement with these boxes only takes around 10 twenty-four hour periods. Short-term boxes can be used at any time of year. Nevertheless, the results they give are not as accurate as long-term measurements.

What do you do about high radon levels?

There are a couple of different ways of dealing with high radon levels. One of the most common ways is to simply increase the ventilation to reduce the concentration of radon in the air.

Radonova’s radon measurements get top marks from Europe’s leading radiation protection body

By | News | No Comments

Radonova Laboratories has achieved excellent results in reference tests.

The reference tests was finally conducted by the German Federal Office For Radiation Protection (Bundesamt für Strahlenschutz – BfS). Comparative tests of four different radon samples show us that Radonova’s results in all cases differ. This with less than ten percent from the respective reference value.

The BfS is Europe’s leading player in the calibration of radon measurement equipment. One of the few accredited to calibrate based on ISO 17025 standard.

All radon doses are exposed to different levels of radon in this current reference tests. Then after that they are compared with the official reference values that are specified by BfS.

“Radonova has consequently been participating in comparative tests of this kind for many years, and we achieve consistently good results. The latest test results are also a confirmation that we are right at the forefront when it comes to reliable radon measurements”. Says the CEO of Radonova Laboratories, Karl Nilsson.

reference tests

“The comparative tests by the Bfs are probably the most demanding anywhere. They certainly set extremely high standards at all stages. It feels good to have our capacity confirmed by an actor like BfS. It is important that our customers should always associate Radonova with the highest quality and reliability”.

Radon Workshop – Radonova’s measurement expert attends IAEA meeting

By | News | No Comments

Radon issues call for international coordination

As part of the work of improving coordination and contributing to more uniform processes for analysing and measuring radon, the IAEA recently organised a radon workshop in Sarajevo. José-Luis Gutiérrez Villanueva from the Swedish company Radonova was present as a specialist in radon measurement. We put some questions to José-Luis, who is one of Europe’s leading experts in this field.

Why is a radon workshop of this kind significant?

Its an important forum, this meetings. We can study all findings from different countries and can share them with others. It is also an important meeting-place for those countries that are not members of the EU and hence covered by EURATOM BSS but are in the IAEA and covered by IAEA BSS. In that sense, the IAEA radon workshop gives us a broad and effective platform for exchanging knowledge.

In what way is it important to have an international perspective on the question of radon?

By looking at this from a global perspective, we can see the differences in the way various countries handle the problem of radon. Although there are international guidelines and regulations.  There are big differences in the work done and the radon programmes in different countries. A radon workshop meeting of this kind helps us to exchange knowledge. Also to reach a common understanding of how best to approach the work. In this case, we were particularly interested in how databases and analyses of statistics from different studies can be used.

What would you say is the biggest challenge if we look at radon as a global problem?

One of the major challenges is how to communicate around issues concerning radon in general and the risks in particular. The differences in priorities and judgment of risk areas are one example. Different countries can arrive at different risk assessments and classifications even though the geological conditions are basically the same.

radon workshop

José-Luis Gutiérrez Villanueva has worked on radon issues and radon workshops for the last 15 years. He wrote his PhD on ‘Radon exposure in dwellings of lung cancer patients: case-control study’ (University of Cantabria, 2016), and is an expert in data analysis and different ways of measuring radon. As secretary of the European Radon Association, José-Luis also has extensive experience of international work with radon .

IAEA is short for the International Atomic Energy Agency. BSS stands for Basic Safety Standards.

The title of the event held in Sarajevo from 12-14 June 2018 was ‘Regional Workshop: on database and statistical analyses, harmonisation of protocols and procedures for the measurement of radon’.

Matrasses have high levels of radon gas in Korea

By | News, Uncategorized | No Comments

Korean radioactive beds matrasses

A recent news published in a Korean newspaper has drawn international attention: bed matrasses may be a source of radon gas

The radioactive Korean matrasses

In May 2018, the Korean government confirmed high levels of radon gas exhalation in some beds. Due to that, some beds could be a source of radon gas.

Are matrasses dangerous?

First investigations found out that exhalation levels were 10 times higher than the reference level. Radon gas is the second leading cause of lung cancer after smoking. Therefore, beds caught the interest of Korean authorities.

What’s next?

Consumers associations have started actions in the court against the company. In addition, the Korean government has withdrawn all matrasses and asked for expert advice.

A town in Galicia with elevated radon levels

By | News | No Comments

galicia Costa da morte

A small town in Northwestern Spain has cancer cases 7 times higher than the Spanish average. The town is located in A Coruña, a province in the Autonomous Region of Galicia. Furthermore, this region has high radon levels.

The little town in Galicia: facts

This town has 313 inhabitants and cancer cases account for 23 only on an 800 m road. Also, the rest of the town has a big incidence of cancer cases.

Why?

This region is one of the Radon Priority Areas in Spain. As a result, the high number of cancer cases in this town might be attributable to elevated radon levels. Other public buildings in Galicia have similar radon-related problems.

Available tools

The EURATOM BSS 59/2013 Directive establishes a reference level for radon of 300 Bq m-3 and mandates member states to set up national radon action plans.
